Participating laboratories report weekly to CDC the total number or RSV tests performed that week, and the number of those tests that were positive. Because reporting delays may be expected for some laboratories, data shown for the most recent weeks, in particular the most recent two weeks, may be less complete than others. Each point on the trend graphs below displays the average number of RSV tests that were performed, and the average percent of those that were positive from three adjacent weeks: the specified week, and the weeks preceding and following it. This is also known as a centered 3-week moving average. The RSV detection graphs below display the 5 week moving average (average of the 4 previous and current weeks) in accordance with the recommendations for assessing RSV trends by detections.
In the United States, annual community outbreaks of RSV infections typically occur during late fall, winter, and early spring. There may be variation in the timing of outbreaks between regions and between communities in the same region.
